OBJECTIVE: To introduce a novel method to successfully remove organized hematoma. Endoscopic evacuation can be troublesome in some patients with a large amount of blood clots or organized hematoma.

METHODS: We retrospectively reviewed medical records of 15 patients who were treated with a so-called "suction and fishing method" for severe clot retention. A large-bore catheter connected with a wall suction unit was inserted into the bladder through the resectoscope sheath, and subsequently a large volume of urine retention and quite a substantial amount of soft clots were removed (suction step). After awhile, negative pressure could not work when the catheter met large and organized fragments of blood clots. In this situation, large blood clots hanging on the catheter tip were removed by gently removing the catheter (fishing step).

RESULTS: In all patients, clot retention was successfully managed with this method. Clot evacuation was performed without anesthesia in 9 patients when electrocauterization was not planned, and opioid analgesics were sufficient for pain control. In the other 6 patients, clot evacuation and fulguration were performed under anesthesia. Median time for clot evacuation was 20 minutes (range 5-55) and median estimated volume of clot evacuated was 200 mL (range 50-600). There was no procedure-related complication such as bladder rupture.

CONCLUSION: The suction and fishing method is a simple, safe, and successful way to evacuate severe organized clot retention. It can resolve intractable clot retention and rapidly relieve related symptoms without anesthesia.
